Y Be it known that I, EDWARD H. SrIILEY,

St. Paul, in the county of Ramsey` and State of Minnesota, have invented a new and useful Improvement in Cuspidors, of which V,the following is a specification.

"3'1""The object of thisV invention is the Aproduction of a bubble fountain cuspidor, for use by dentists, and nose and throat specialists.` My invention providesin combination with a dental cuspidor a bubble drinking fountain, -which dispenses.Y with drinking and'rinsing cups commonly used by dentists. The ,use of my invention lessens the possibility of contamination and infectionfrom. the use of cups where there fis the greatest danger inasmuch as a great many cases under treatment having diseased conditions of the oral cavity, are compelled to use some rmeans of rinsing Vand cleaning` out the debris, pus and blood `from the mouthfdue to operations on the teeth or throat, while in therchair. The invention providesa bubble drinking fountain above the cuspidor, `which co-acts with the cuspidor by catching the `overiow from the fountain and using` saidovertlowfor cleaning the cuspidnrbowl before it is conducted through a waste pipe. This fountain is provided with a removable tip made of porcelain or glass,\whereby the tip and fountain can be cleaned and sterilized, the tip being easily and quickly Vremovable for that purpose, should it be contaminated by blood or pus of any-kinder touch by the lips or4 fingers of the patient, andanother tip previously sterilized substituted. Among other features of advantage by the use of my invention are convenience'to dentists in dispensing with the care of cleaning the drinking glass, the unsightly appearance of said `glass when soiled, the time saved in cleaning, the convenience `and comfort to the patient in dispensing with the use of a glass and the feeling of safety from infection and contamination. o

In the accompanying drawing forming part of this'specification, Figure 1 is a side elevation of my invention, a portionV of the structure being broken away and 1nscct1on`;

Fig. 2 is a side elevation of the tip employedin thebubble fountain, and Fig. 3 is a section of a detail taken on the line X-X of Fig. 1.

bowl, which is seated in the usual waste pipe n tting 2. j This waste pipe tting is pivoted a citizen of the United States, residing `at to swinghorizontally in the usual manner ini the end of a bracket 3, which is mounted upon the vertical stem l on theside of a dental chair or other support not illustrated. The waste pipe 2 is connected below the bracket 3 with a flexible waste tube 5 in the usual manner, and projecting from the side of the waste pipe 2 is a branch waste pipe 6 rising vertically and connected to the side of the bowl A to act as an overflow waste lconductor should the bowl become too full. The branch waste pipe 6 extends upwardly above its `connection with the bowl and has a branch conductor in the form of a `bracket '7 upon the outer end of which a receptacle. |The bracket 7 contains a channel 10, acting as a drain for said sterilizuingreceptacle when desired, a plug 1`Obe- ,ing inserted in the oriice of said channel when it isdesired to retain water in the receptacle `for sterilizing purposes. The side of the branch is formed with a bracket 11,

in which the water supply pipe 12 is vertically slidable, it being held in vertically se lectedposition bythe set screw 13 in the end of the bracket 11. This water supply pipe is shown connected with a iexible water supply tube 14, which is adapted to be connected with a source of water supply not illustrated. The water supply pipe 12 carries a valve itting 15 which is opened and closed by a handle 16. This fitting has tapped therein a duct 17, and a branch 18 which is properly adjusted inside the bowl to project and whirl water around the inner surface thereof. The portion of said duct between its ends dips down into the bowl, and the outer extremity of the duct projects upwardly above the central portion of the bowl, and carries thereon a bubble fountain fixture C.

This bubble fountain consists of a. base member` in the form of a' cup 19 threaded upon the extremity of said duct,and has projecting inwardly from its inner surface on its upper end a pair of suitably spaced key lugs 20. Arranged inside of this cup is a tipD in the form of a hollow cylindrical wall 22 having on one end an enlarged head or mouthpiece 23. The periphery of this Eeploi et thm patent' may' be obtained 61* head is curved and projects beyond the Wall of the cup 19, and contains therein an enlarged circular pasag' '24' leading' ffin the" space in the cylindrical portion of the tip, said enlarged openingl terminating in a eniall orifice 25 at the crown ofV the device, The periphery of the cylindrical portion of the tip is formed With a plurality of lock shoulders 26, which are diametrically oppo- Site and adapted to' passv down belovv` the lugs 2U and inter-'look therovvith by turning;l the tip after it h'albeeii inserted in the cup; In
